There are further meanings of `block' in mathematics, see e.g. Block Theory and Block Design.

Well, add them. This is a Wiki after all, be bold. Dysprosia 14:11, 20 January 2006 (UTC)[reply]

This page is difficult to understand because groups have an order, but sets do not. The difficulty is with the word "fix": it is not obvious what fixing means. It is clear however that the author is thinking of a totally ordered set, and that fact should be made explicit. —Preceding unsigned comment added by SergioPi (talkcontribs) 13:07, 8 October 2010 (UTC)[reply]

I don't think it's difficult to understand. The only place where "fix" is written is: "gB=B (g fixes B)". It doesn't have to do anything with totally ordered sets. (X is nothing else but a set on which G acts.) And of course "g fixes B" just means "gB=B for all g in G". (gB=B is a short version of {gb|b in B}=B.) —Preceding unsigned comment added by 93.129.49.238 (talk) 08:49, 3 March 2011 (UTC)[reply]
